The document discusses DevRain Solutions' software development process for outsourcing teams. It outlines their expertise, development methodology, tools used, and highlights for mobile app development. The process focuses on avoiding common mistakes through good management, communication, and using best practices and tools for collaboration, source control, documentation and more. Estimation models and highlighting key stages like prototyping and testing on real devices are also covered.

1. Software development process
for outsourcing team

2. What makes you unique
1. Deep expertise and rich portfolio
2. Avoiding common mistakes
3. Good management and development process
4. Using best tools

4. Development is non-linear process
1. Increasing number of team
members == increasing of
communication complexity
2. Development is not about time
and resources, it is about people
and services
3. Productivity of junior/middle
developer and “guru” may differ
up to 5-10 times

5. Error cost (cone of uncertainty)
At the beginning of any project we
don’t know exactly how long a
project is going to take.
No two ever projects have:
• The same requirements
• The same people
• The same business context
• The same technology
• The same priorities & constraints

6. Parkinson's Law
Parkinson's Law states
that work expands to fill
the time available for it.
Result? Extra time gained
is wasted.

7. Zone of improbability
9 women can’t make a baby in a month
*25% - max volume of project squeezing time
Fred Brooks “Mythical man month”, 1975

8. “Zero” stage
Estimation, environment installation (staging
and production), creating accounts for all
team members, understanding roles and
management flow
*it’s good to have “zero” stage completed as soon as possible

9. Simple estimation model
Hourly rate * hours * 1.3 = project cost
~30% - project risks (employees search, bug fixing, requirements missing, illness, lacks of
communication, lazy developers)
Payable hour != standard hour

10. Two estimations (best/worse cases)
(Cbc * Pbc) + (Cwc * Pwc)
• Cbc – cost (best case)
• Pbc – probability (best case)
• Cwc – cost (worse case)
• Pwc – probability (worse case)
Real cost will be higher than best/worse
average cost.

11. Quick estimation for mobile apps
• iOS (iPhone + iPad)
• Windows Phone + Windows 8
• Android
Assume Windows Phone = 1 unit
1 (WP) + 0.75 (Win8) + 1.5 (iPhone) + 0.5 (iPad) + 2 (Android) =
5.75 (units)

12. Different goals
Customers are worried about business
Developers are worried about technologies and ideal code

13. Communication
Ask yourself do you know:
• who determines the business strategy of
the project?
• who will evaluate the quality of your
work and what is “project done” criteria?
• how many bosses do you have?
• who has the final voice in decisions?

14. Roles not titles
Job title == many roles
1. Every team member should
know his roles.
2. Avoid too many “bosses”
(ideally just one).

15. Funnels (measure user conversion rates)
Give your customer such
answers:
• how many users logged in?
• how number of logins changed after
implementing a new design?
• how many users navigated from page
1 to page 2?
• how many users clicked such button?
• etc.

16. Process highlights
1. With integration to customer’s process
Team should be totally aware with customer’s business process.
2. Without integration to customer’s process
Teams use own process internally and use a “public interface” to customer’s business
process. Interfaces can be differ with different customers.
3. Orientation on result, not the process
Agile is not good in all 146% cases. Sometimes F*ckup Development works better.

17. Process highlights
1. UX/UI & guidelines & graphic design
Exactly in this order
2. If development for several platforms
Make at least alpha version for the one platform with real data, than – other platforms
3. Avoid “not invented here” philosophy
Don’t hesitate to use already existing products, research, standards, or knowledge even if
they are paid.
4. Use best tools
Collaboration & communication, storage, documents exchange, source controls, tasks
management, Wiki & CRM, feedback etc.

18. What tools we use
UX/UI, collaboration, communication, source control, docs
management, education

19. UX/UI & Prototyping
SketchFlow:
• Windows Phone, XAML apps;
MockupBuilder, Balsamiq:
• sketchy wireframes;
• UI components & icons;
• drag & drop simplicity;
• click-through prototypes.

20. Collaboration
Yammer:
• Freemium enterprise social network
service that was launched in 2008 and sold
to Microsoft in 2012
• Yammer is used for private communication
within organizations and is an example of
enterprise social software
• Access to a Yammer network is determined
by a user's Internet domain so that only
individuals with appropriate email
addresses may join their respective
networks

21. Communication
Skype:
• for small group conversation;
• share screen, group video chat (premium).
Lync:
• for big groups (webinars);
• easy recording, powerful interaction
features.
Live Meeting:
• for webinars.

22. Source control
TFS Online:
• cloud based;
• free for small groups;
• natively integrated with Visual Studio.
Alternatives:
• Bitbucket.com;
• Github.com.

23. Other tools
OneDrive & Dropbox
For files storage
Google Docs & Office 365
& DocuSign
For docs management
Asana
For task management

1. Usability – first, design – second
2. Testing on real devices or use 3rd party services
3. Application update flow (and delays because of certification
process)
4. Feedback and errors management
5. Guidelines and OS features integration
6. Most of mobile apps development projects are short-term
